Cold prevention measures of grape in winter

As a very popular fruit, grape has a large planting area in all parts of our country. Now, with the passage of time, the temperature is getting lower and lower, and it is gradually entering winter. Winter grapes gradually enter the dormant period. After entering the dormant period, the cold resistance of grape plants will also decline. So we need to do a good job of cold prevention in winter, so let's take a look at the cold prevention measures of grapes in winter with Xiaobian.

1. The method of preventing cold by burying on the ground

The cold protection method buried on the ground is a common cold protection measure for grapes in winter. First of all, the grape plant will be cut in winter, and then the branches will be combed off the shelf in the same direction and squared on the ground. Be careful not to let the branches be broken. Cover some grain straw on and around the base and branches of the plant to keep warm. Then the soil is compacted, and there should be no cracks when covering the soil, so as to prevent the invasion of thieves and affect the growth of branches. The height of the mound is usually maintained at about 40cm, and after the soil is frozen, pour in an appropriate amount of frozen water.

2. Underground trenching and burying method

In addition to burying on the ground, we can also dig trenches underground to prevent the cold. First of all, at the edge of the grape plant, about 40cm from the root system, dig a trench along the row with a depth and width of about 50cm. Then, as with the actual burial on the ground, the branches are combed and tied up and put into the ditch. After putting it into the ditch, in order to improve the cold protection effect, it is also necessary to cover an appropriate amount of straw and other straw materials for heat preservation, and then compacted in the covered soil. It should be noted that although this cold protection effect is very good, it should not be used year after year, otherwise it will harm the roots of the plant.

3. Cold proof method of planting in deep trench

The cold protection method of planting in deep trenches requires that everyone should start to prepare when planting. First of all, when we plant grapes, we have to dig deep trenches to plant grapes. The depth of the trench is kept at about 40cm, and then it can be planted according to the usual grape planting method. Grape plants will grow directly in deep trenches. After winter, we can choose whether to bury the soil in the ditch according to the actual situation, and its cold-proof effect is very good.

4. Cold protection with plastic film

The cold protection method of plastic film is also a cold protection measure often used by many fruit growers in winter. First of all, the grape vines should be covered with some straw and grain straw, then covered with a film, and then tightly covered with soil. In the operation, we should pay attention to the non-destructive film, and also pat the soil solid, otherwise it is basically unable to achieve the cold-proof effect. The cold protection effect of this method should be the best, because rice straw, film, soil and so on can protect against the cold, and the overwintering survival rate of grapes will also be very high.

The above is a brief introduction to the cold protection measures of grapes in winter. That's all for today's introduction. This article is for reference only. I hope it can be helpful to everyone.
